SKI BOOTS: all Scarpa ski boots are measured in Mondo sizing*highlighted (or not) sizes share the same shell size; the liners are lasted for each 1/2 size*some skiers may want to downsize up to 1 full Mondo size, depending upon personal preference

Is this shoe basically like the bottom...

Good question. The bottom of the Scarpa Zen Multisport Shoe - Men's and the Scarpa Kailash are different as they both use different sole treads from VIBRAM and the Zen has EVA cushioning while the Kailash uses the sole only for cushion. Also, the Kailash has a smaller toe rand on the end than the Zen as the Zen can be used as an approach shoe while the Kailash is more for backpacking.
